A spraying device comprising a heat-responsive bimetal whose dimension changes with change in temperature and is movable to actuate a valve for opening and closing a passage through which a pressurized fluid is sprayed from a container into the atmosphere and means are provided for manually actuating the valve through the bimetal. The manual actuating means is effective for spraying the pressurized liquid at a desired stage even if the bimetal is in such a condition that it can not actuate the valve due to low temperature thereof. |
